Abstract:
... The western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), is one of the most severe pests of cultivated maize, Zea mays L. Most of the damage to this crop is caused by larvae feeding on the root system, causing important economic costs in terms of yield losses and management efforts.This research was carried out to evaluate the effect of different chemica ...

Abstract:
... The soil-borne fungus Rhizoctonia solani causes damping-off on sugar beet seedlings. Growers rely on fungicides to protect sugar beet in fields affected by R. solani. Quinone outside inhibitor (QoI) fungicides, such as azoxystrobin, have been applied as in-furrow and foliar sprays to manage R. solani, but repeated use of QoI fungicides pose risks in fungicide resistance. Penthiopyrad is a novel fu ...
